Theme: Latin Square
Author/Opus: This is the 4th puzzle from guest contributor and site patron Chris Green.
Rules: Standard LITS rules. Also, as in “Easy as LITS”, the letters outside the grid indicate the first tetromino encountered in the corresponding direction. Also, as in “Signpost LITS”, some cells or groups of cells are outlined and labeled with a letter. If any of these cells is shaded, then the tetromino shape must match the clued letter.
Answer String: Enter the length in cells of each of the shaded segments from left to right for the marked rows, starting at the top. Separate each row’s entry from the next with a comma.
Time Standards (highlight to view): Grandmaster = 8:45, Master = 11:00, Expert = 22:00
